The advantages of the virtual prototype are summarized. The topology and degree of freedom of the artillery are discussed. The local coordinate system of each body is established. Introduced the application of ADAMS to the field of equipment simulation for the first time, introduced the steps of establishing ADAMS and equipment virtual prototype of mechanical system, and established the equipment virtual prototype in ADAMS environment with Fortran language programming. The simulation results of the example prove that the weapon equipment model And the establishment of its virtual prototype correctness. Based on the simulation of virtual prototype, a scheme of artillery fault assessment was developed and the concept of fault judgment function was proposed. Finally, the prospect of virtual prototype technology in the field of weaponry and equipment is forecasted
